Title: Positive solutions and eigenvalues of nonlocal boundary-value problems Authors: Jifeng Chu (Hohai Univ., China) Zhongcheng Zhou (Southwest Normal Univ., China) Abstract: We study the ordinary differential equation $x''+\lambda a(t)f(x)=0$ with the boundary conditions $x(0)=0$ and $x'(1)=\int_{\eta}^{1}x'(s)dg(s)$. We characterize values of $\lambda$ for which boundary-value problem has a positive solution. Also we find appropriate intervals for $\lambda$ so that there are two positive solutions.
